In my humble opinion,So-called Price Action is just the classical technical analysis which follows Dow Theory,the key is trend,define trend,find trend,use trend(anti or follow ).What price gives us directly? Price patterns(bars) and swing highs/lows. Price patterns contribute to top and bottom,swing highs/lows lead to trend S/R lines and lines.
BUT,the principle of commerce is person,the plan of commerce is different.It depends on how we LOOK the items prices give us.right or incorrect?! Technical analysis is experiential,so does the price action.
